How to Make Loaded Chicken and Cajun Sausage Pasta Casserole Recipe
Step 1: Prep Your Oven and Pasta
Start by preheating your oven to 375°F (190°C) and lightly greasing your casserole dish to prevent sticking. Cook the penne pasta until it is just shy of al dente based on package instructions, then drain and set it aside. This ensures the pasta won’t overcook during baking and maintains a pleasant bite.
Step 2: Cook the Chicken
Heat olive oil over medium-high heat in a large skillet. Add your diced chicken and season it with half of the Cajun seasoning. Let the chicken cook undisturbed for a few minutes until it turns beautifully golden and is cooked through. Then, remove it from the skillet and set it aside to keep the flavors intact and avoid overcooking.
Step 3: Brown the Cajun Sausage
In the same skillet, add the sliced Cajun sausage and cook for a couple of minutes until it starts to brown and release its smoky aroma. Remove it from the pan and set aside with the chicken so all the proteins stay juicy and flavorful.
Step 4: Sauté Your Veggies
Lower the heat to medium, then toss in the chopped onions and red bell peppers. Sauté these until they soften and become fragrant, about 3-4 minutes. Stir in the minced garlic and cook for an additional minute, letting the garlic release its inviting aroma without burning.
Step 5: Create the Creamy Sauce
Add chicken broth, heavy cream, the remaining Cajun seasoning, and the diced tomatoes with green chilies to the skillet. Stir everything together and bring it to a gentle simmer. This combination melds the spicy, creamy, and savory flavors that embrace the pasta and proteins.
Step 6: Combine Pasta, Chicken, and Sausage
Return the cooked pasta, chicken, and sausage back to the skillet. Toss everything together carefully so the creamy sauce coats every piece. Taste and season with salt and pepper to ensure the flavor is balanced and vibrant.
Step 7: Assemble and Bake
Transfer your pasta mixture into the prepared casserole dish. Generously top with shredded mozzarella and sharp cheddar cheeses. Pop it in the oven and bake for 18-20 minutes until the cheese melts and bubbles enticingly. For an extra golden, crispy top, broil for 2-3 minutes at the end.
Step 8: Rest and Garnish
Remove the casserole from the oven and let it rest for a few minutes. This resting time helps the sauce settle and makes serving easier. Sprinkle freshly chopped parsley on top before serving for a fresh pop of color and flavor.

Garnishes
A simple sprinkle of fresh chopped parsley brightens up the rich casserole visually and adds an herbaceous note. For extra flair, a few thinly sliced green onions or a dash of smoked paprika on top can add excitement both in flavor and appearance.
Side Dishes
This casserole is hearty enough to stand on its own but pairs beautifully with a crisp green salad dressed in a light vinaigrette or steamed vegetables like green beans or broccoli to add freshness and balance the creamy richness.
Creative Ways to Present
For a festive touch, serve this casserole in individual ramekins or mini casserole dishes. You could also turn leftovers into a casserole-inspired pasta bake by reheating and topping with an extra handful of cheese for a bubbly crust. Presentation with a vibrant serving ladle and rustic bread on the side also invites everyone at the table to dig in happily.
Make Ahead and Storage
Storing Leftovers
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen after sitting for a bit, making for an even tastier meal later on.
Freezing
You can freeze this casserole before baking by covering it tightly with foil and plastic wrap. Freeze for up to 2 months. When ready, bake it straight from the freezer, adding extra time to ensure it heats through fully and the cheese melts delightfully.
Reheating
Reheat individual portions in the microwave or warm the casserole in the oven at 350°F until heated through. To keep the top from drying out, cover with foil during reheating and remove foil in the last few minutes for a fresh melted cheese finish.
FAQs
Can I use a different type of pasta for this casserole?
Absolutely! While penne is ideal for holding the sauce, other short pasta shapes like rotini or rigatoni would also work wonderfully in this recipe.
Is there a way to make this dish less spicy?
To tame the heat, reduce the amount of Cajun seasoning or use a mild sausage instead of spicy Cajun sausage. You can also omit the diced tomatoes with green chilies or replace them with regular diced tomatoes for a gentler flavor.
Can I substitute the heavy cream with something lighter?
If you want a lighter dish, you can try using half-and-half or whole milk, but keep in mind that the sauce will be less rich and creamy. Adding a bit of flour or cornstarch slurry can help thicken the sauce.
What if I don’t have smoked Cajun sausage?
You can substitute with any smoked sausage or even chorizo for a different yet delicious smoky flavor. Just adjust the seasoning to taste to maintain the right balance of spice.
How do I make sure the pasta doesn’t get mushy?
Cooking the pasta just shy of al dente and allowing the casserole to rest after baking prevents overcooking. Also, avoid soaking the pasta in the sauce too long before baking to maintain perfect texture.
